Every action has equal and opposite action. There is gravitational force and it pulls us towards it center and A FORCE FROM EARTH is being applied on our body.This is supporting force or Normal force. Weight is the force of gravity applied on our body by earth and If Earth pulls by X Newton of energy then a force from Earth is also coming of X Newton. when we stand on Bathroom Scale than our weight is shown by scale . HOW??? Gravitational force+ Normal force = 0 Then how weight is scaled.
